No. 61/477,021, entitled “Electrical Accessories and Associated Methods of Use and Manufacture,” filed Apr. 19, 2011, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

This invention generally relates to electrical accessories, and more particularly relates to electrical accessories and associated methods of use and manufacture.

BACKGROUND OF THE INVENTION

Electrical junction boxes, also known as outlet boxes, are utilized to provide termination and connection points for electrical wiring as well as data, communication, and control wiring. Generally, electrical wiring in residential and commercial construction will be installed in the walls or ceilings of the construction, and one or more electrical junction boxes can be provided at various points along the wiring to permit the installation of associated electrical switches, electrical outlets, and other devices such as lights, fans, etc. In some instances, such as for wall mounted switches or electrical outlets, an installer may need a certain length of exposed electrical wiring to connect a switch or outlet to the electrical wiring. In such instances, the exposed electrical wiring should be contained within the junction box to protect residents and/or commercial workers from electrical hazards associated with exposed electrical wiring.

Conventional metal electrical junction boxes can be mounted using a variety of brackets and other mounting means. However, the number of different conventional metal electrical junction boxes combined with the variety of brackets and other mounting means creates the need for providing ever increasing amount of inventory space for a manufacturer, supplier, or retailer to offer these products to a consumer. In addition, the number of SKUs (stock keeping units) or unique identifiers and associated time spent tracking this inventory can be burdensome and expensive.

DETAILED DESCRIPTION OF EMBODIMENTS

Example embodiments of the invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

The terms “electrical junction box,” “electrical accessory,” “electrical junction box,” “outlet box,” “junction box,” and their pluralized forms are used interchangeably throughout this specification, and are intended to refer to a receptacle or device enclosure used for mounting or affixing electrical wires to or within a receptacle or device enclosure, which can in turn be mounted to a wall, wall stud, ceiling, or ceiling stud.

The terms “modular bracket,” “mounting bracket,” and their pluralized forms are used interchangeably throughout this specification, and are intended to refer to a device mounted to an exterior wall or surface of an electrical junction box.

The terms “mount,” “mounting,” “mounting device,” and “modular attachment,” and their pluralized forms are used interchangeably throughout this specification, and are intended to refer to an apparatus, device, or technique for connecting a modular or mounting bracket to an electrical junction box.

The term “predefined universal distance” is intended to refer to a preselected distance between the centers of at least two mounting holes in a wall of an electrical junction box. The preselected distance is typically selected based at least in part on the surface area of the wall of the electrical junction box, the sizing and spacing of knockouts on the wall of the electrical junction box, and the relative sizes of some or all electrical junction boxes in the same family or group of electrical junction boxes.

In accordance with example embodiments of the invention, modular brackets, mountings, and knockouts for electrical junction boxes and associated methods of use and manufacture are provided. Modular brackets and mountings for electrical junction boxes can be made to mount a variety of electrical junction boxes with different shapes and sizes. For example, a modular bracket and mounting for an electrical junction box can be configured to mount to one or more different sized and/or shaped electrical junction boxes including, but not limited to, a single gang, rectangular-shaped electrical junction box, a double gang rectangular-shaped electrical junction box, a square-shaped electrical junction box, a round electrical junction box, a hexagonal-shaped electrical junction box, or an octagonal-shaped electrical junction box. The term “modular” used in this specification generally refers to the interchangeability of a particular bracket to be mounted to multiple different sized and/or shaped electrical junction boxes. For example, a modular bracket of interest may be configured to be mounted to multiple sizes of electrical junction boxes including, but not limited to, a single gang, rectangular-shaped electrical junction box; a double gang rectangular-shaped electrical junction box; a round electrical junction box; and an octagonal-shaped electrical junction box.

In accordance with other example embodiments of the invention, knockouts for electrical junction boxes can be formed in electrical junction boxes with different shapes and sizes. For example, one or more knockouts for an electrical junction box can be selectively sized and oriented in one or more different sized and/or shaped electrical junction boxes including, but not limited to, a single gang, rectangular-shaped electrical junction box, a double gang rectangular-shaped electrical junction box, a square-shaped electrical junction box, a round electrical junction box, a hexagonal-shaped electrical junction box, or an octagonal-shaped electrical junction box. For example, a knockout of interest may be configured to be mounted to multiple sizes of electrical junction boxes including, but not limited to, a single gang, rectangular-shaped electrical junction box; a double gang rectangular-shaped electrical junction box; a round electrical junction box; and an octagonal-shaped electrical junction box.

Modular brackets and mountings for electrical junction boxes and associated methods of use and manufacture of such modular brackets and associated electrical junction boxes provided by certain embodiments of the invention can provide various technical effects and/or solutions. In certain instances, modular brackets and mountings for electrical junction boxes can reduce time and costs in storing, assembling together, and mounting the modular brackets and electrical junction boxes. Contractors, end users, and installers can benefit from using various embodiments of the invention since modular accessories can provide greater installation versatility, wherein many more configurations may be possible and the availability of some fixed configurations may be challenging.

Knockouts for electrical junction boxes and associated methods of use and manufacture of such knockouts and associated electrical junction boxes provided by certain embodiments of the invention can provide various technical effects and/or solutions. In certain instances, knockouts for electrical junction boxes can reduce time and costs in storing, assembling together, and mounting the modular brackets and electrical junction boxes.

FIG. 1 illustrates a perspective view of an example modular bracket, mountings, and electrical junction boxes in accordance with an embodiment of the invention. FIG. 1 illustrates an example single gang, rectangular-shaped folded electrical junction box 100 and a double gang, square-shaped folded electrical junction box 102 ready for installation or use with a modular bracket 104 by a user or consumer in accordance with an embodiment of the invention. Each junction boxes 100, 102 can include one or more spaced apart holes 106 on at least one sidewall 108 of the boxes 100, 102 to receive a respective number of mounting devices 110 associated with the modular bracket 104. In this example, the smaller rectangular-shaped box 100 can include spaced apart holes 106 near the upper open edges of all four of the sidewalls 108, 112, 114, 116. The spaced apart holes 106 are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using a common modular bracket with mounting devices, such as 110. For example, a predefined universal distance for the electrical junction box shown as 100 in FIG. 1 and/or for a similar family or group of electrical junction boxes can be approximately 0.5 inches to 3.0 inches, such as about 1.0 inches (2.54 cm). Likewise, the larger square-shaped box 102 can include spaced apart holes 106 near the upper open edges of all four of the sidewalls 118, 120, 122, 124. The spaced apart holes 106 are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using a common modular bracket with mounting devices, such as 110. For example, a predefined universal distance for the electrical junction box shown as 102 in FIG. 1 and/or for a similar family or group of electrical junction boxes can be approximately 0.5 inches to 3.0 inches, such as about 1.0 inches (2.54 cm). Electrical junction boxes with similar shaped spaced apart holes, such as 106, for use with a common modular bracket can be known collectively as a “family of electrical junction boxes.” In other embodiments, an electrical junction box can have other shapes including, but not limited to, square, round, octagonal, rectangular “handy box,” single gang rectangular, double gang rectangular, triple gang rectangular, and other multiple gang shapes. In other embodiments, a rectangular-shaped or square-shaped electrical junction box may have other dimensions such as a deeper or shallower depth than the boxes 100, 102 shown.

The spaced apart holes 106 in the boxes 100, 102 shown in this embodiment can be square-shaped holes. The spacing between the respective centerlines of the holes 104 can be, for example, between approximately 0.25 inches (0.64 cm) and 3.5 inches (8.9 cm), and the holes 104 can be spaced, for example, relatively close to the upper edge of the electrical junction boxes 100, 102, such as approximately 0.25 to 0.5 inches from the upper edge. In other embodiments, other shapes, dimensions, and spacing for the holes in an electrical junction box can be used.

A predefined universal distance or spacing between holes for a modular or mounting bracket in accordance with an embodiment of the invention, such as spaced apart holes 106 in FIG. 1, can be selected based at least in part on the surface area of one or more sidewalls for an electrical junction box, the sizing and spacing of knockouts, such as 126, on the sidewalls of the electrical junction box, and the relative sizes of some or all electrical junction boxes in the same family or group of electrical junction boxes. In any instance, the predefined universal distance or spacing between holes for a mounting bracket in accordance with an embodiment of the invention can be consistent or otherwise closely similar to the distance between holes in a family or group of electrical junction boxes. In this manner, a common modular or mounting bracket can be used with multiple electrical junction boxes of different sizes and/or shapes, thus reducing time and costs in storing, assembling together, and mounting the modular or mounting brackets and electrical junction boxes.

According to an embodiment of the invention, an example method for determining a predefined universal distance and the sizes and locations of various features, such as knockouts, for an electrical junction box is described with respect to FIGS. 138-146.

The modular bracket 104 shown can include two mounting devices 110, though in other embodiments, a fewer or greater number of mounting devices can be employed. The mounting devices 110 shown in FIG. 1 are protrusions with a relatively narrow body portion extending from the surface of the modular bracket 104 with both protrusions terminating with relatively wide flared head portion. The mounting devices 110 shown in FIG. 1 are correspondingly spaced apart a predefined universal distance, similar to the spaced apart holes 106 in FIG. 1. The mounting devices 110 are shown by way of example only, and other mounting devices can be used in other embodiments. In use, the modular bracket 104 can mount adjacent to one of the sidewalls of either electrical junction box 100, 102, such as sidewall 108 or 118, when the mounting devices 110 are inserted through respective holes 106 in the sidewall 108 or 118. After each mounting device 110 is inserted through respective holes 106, the shape and configuration of the mounting devices 110 maintain the relative positions of the box 100, 102 and modular bracket 104 in a substantially adjacent orientation. Other modular brackets, mounting devices, and associated holes, and associated configurations, sizes, dimensions, positions, and numbers of modular brackets, mounting devices, and holes in each sidewall and electrical junction box are possible in accordance with embodiments of the invention.

In one aspect of an embodiment, the modular bracket and mounting devices can be made from a single piece or integral material.

In one aspect of an embodiment, a modular bracket and electrical junction box in accordance with an embodiment of the invention can meet the standards specified by UL (Underwriters' Laboratories) 514A.

Other example modular or mounting brackets and mountings for an electrical junction box in accordance with various embodiments of the invention are shown and described below with respect to FIGS. 2-23, and 31-54. Each of the mountings that may be shown in FIGS. 2-23 and 31-54 can be spaced apart a predefined universal distance from at least one other mounting, and used in conjunction with a modular bracket, such as 104, for use in mounting the modular bracket to a wall or sidewall of an electrical junction box, similar to 100 or 102. Furthermore, the various electrical junction boxes that may be shown in FIGS. 2-23, and 31-54 can include or otherwise be modified to include a pair of spaced apart mounting holes, similar to 106 in FIG. 1, near the upper open edges of the sidewalls. The spaced apart holes of these electrical junction boxes are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using a common modular bracket with mounting devices, similar to 110.

One will recognize that modular or mounting brackets and mountings in accordance with embodiments of the invention can be used with plaster ears, old work clips, far side box supports, and other electrical, data, communication, and control accessories.

Also shown in FIG. 1 is a series of knockouts 126 oriented in each of the sidewalls 108, 112, 114, 116, 118, 120, 122, 124 of the electrical junction boxes 100, 102 shown. Two knockouts 126 are shown in each of the longer sidewalls 106, 112 of the rectangular-shaped box 100, and one knockout 126 is shown in each of the shorter sidewalls 110, 114 of the rectangular-shaped box 100. The knockouts in the rectangular-shaped box 100 are, for example, all double knockout configurations with concentrically-shaped or eccentrically-shaped knockouts of ¾ and 1 inch sizes. In the square-shaped box, two knockouts are shown in a pair of opposing sidewalls 118, 122, and three knockouts are shown in the other pair of opposing sidewalls 120, 124. The two knockouts in the sidewalls 120, 124 of the square-shaped box 102 are two different sized triple knockout configurations with concentrically-shaped or eccentrically-shaped knockouts, the first including ½, ¾, and 1 inch sizes, and the second including ¾, 1, and 1¼ inch sizes. The three knockouts in the sidewalls 118, 122 of the square-shaped box 102 include two similar sized double knockout configurations with concentrically-shaped or eccentrically-shaped knockouts, these including ¾ and 1 inch sizes, and further including a triple knockout configuration with concentrically-shaped or eccentrically-shaped knockouts with ½, ¾, and 1 inch sizes. Other knockout configurations, sizes, dimensions, positions, and numbers of knockouts in each sidewall and electrical junction box are possible in accordance with embodiments of the invention.

In one aspect of an embodiment, one or more knockouts in an electrical junction box in accordance with an embodiment of the invention can meet the standards specified by UL (Underwriters' Laboratories) 514A.

Detailed views and dimensions for example knockouts for an electrical junction box in accordance with various embodiments of the invention are shown and described below with respect to FIGS. 24-28 and 55-56.

Turning to other examples of modular or mounting brackets and mountings, FIGS. 2-23, and 31-54 are views of example modular or mounting brackets and mountings for an electrical junction box in accordance with various embodiments of the invention. In each of these embodiments, various shaped modular or mounting brackets with one or more mounting devices are shown.

In FIG. 2, a mounting bracket 200 with two different mounting devices 202, 204 is shown. The first mounting device, a pivoting retainer clip 202, is shown with a pair of extended open ends and an intermediate cap shape, wherein the cap shape can provide a spring-like force to maintain the extended open ends in a relatively parallel orientation. The clip 202 is shown in an installed position with respect to a cylindrical-shaped protrusion or clip post 206 extending from the mounting bracket 200. When the protrusion or clip post 206 is inserted into a respective hole of a junction box, the pivoting retainer clip 202 can be installed over the protrusion or clip post 206 to maintain the relative positions of the junction box and the mounting bracket 200 in substantial contact with each other.

The second mounting device, a locking spring 204, is shown in an extended position with respect to another cylindrical-shaped protrusion or second clip post 208 extending from the mounting bracket 200. FIG. 3 shows a side view of the mounting bracket shown in FIG. 2 with the locking spring 204 extending from an upper surface of the other cylindrical-shaped protrusion or second clip post 208 extending from the mounting bracket 200. The locking spring 204 is shown in an extended position, and when depressed can partially retract into the other cylindrical-shaped protrusion or second clip post 208. FIG. 4 shows a side-sectional view A-A of the locking spring 204 shown in FIG. 2.

FIG. 5 shows a side view of the mounting bracket 200 shown in FIG. 2. with a pair of clip posts 206, 208 is shown. The mounting bracket 200 is configured with a relatively wide and long box plate 210 to which the clip posts 206, 208 are mounted to, and is further configured with a relatively shorter but thicker bracket plate 212 mounted to the other side of the box plate 210 from the clip posts 206, 208.

FIG. 6 illustrates a side view of a mounting bracket 600 with a mounting device such as a locking ball mechanism 602. In this example embodiment, the locking ball mechanism 602 can include a protrusion 604 extending from the mounting bracket 600, and a pair of spaced apart lock balls 606 with a spring, such as a V-shaped spring 608, disposed between the lock balls 606. In use, when the locking ball mechanism 602 is inserted through a hole in a junction box, such as 610, the V-shaped spring 608 permits the lock balls 606 to recess within a portion of the protrusion 604 as the mechanism 602 passes through the sidewall of the junction box 610. When the lock balls 606 are substantially through the sidewall, the V-shaped spring 608 permits the lock balls 606 to move away from each other thus permitting the locking ball mechanism 602 to maintain the relative positions of the mounting bracket 600 and junction box 610 in substantial contact with each other.

FIG. 7 illustrates a side view of a mounting bracket 700 with a mounting device such as a V-spring device 702. In this example embodiment, the V-spring device 702 can include a protrusion 704 extending from the mounting bracket 700, and a pair of spaced apart arms 706 connected together at one end, such as a V-shaped spring 708, disposed within the protrusion. In use, when the V-spring device 702 is inserted through a hole in a junction box, such as 710, the V-shaped spring 708 permits the spaced apart arms 706 to recess within a portion of the protrusion 704 as the device 702 passes through the sidewall of the junction box 710. When the spaced apart arms 706 are substantially through the sidewall, the V-shaped spring 708 permits the spaced apart arms 706 to move away from each other thus permitting the V-spring device 702 to maintain the relative positions of the mounting bracket 700 and junction box 710 in substantial contact with each other.

FIG. 8 illustrates a side view of a mounting bracket 800 with a mounting device such as a wire spade device 802. In this example embodiment, the wire spade device 802 can include a retention portion 804, an expanded portion 806, and an extended protrusion 806 disposed between the retention portion 804 and expanded portion 806. In use, when the wire spade device 802 is inserted through aligned a hole in a junction box, such as 808, the expanded portion 806 compresses to permit the device 802 to pass through the hole. When the expanded portion 806 is substantially through the sidewall of the junction box 808, the expanded portion 806 expands, thus permitting the wire spade device 802 to maintain the relative positions of the mounting bracket 800 and junction box 808 and in substantial contact with each other.

FIG. 9 illustrates a side view of a mounting bracket 900 with a mounting device such as an omega clip device 902. In this example embodiment, the omega clip device 902 can include a retention portion 904, a cup or lip 906, and an extended portion 908 disposed between the retention portion 904 and cup or lip 906. In use, when the omega clip device 902 is inserted through a hole in the junction box, such as 910, the lip or cup 906 compresses inwardly to permit the device 902 to pass through the hole. When the lip or cup 906 is substantially through the sidewall of the junction box 910, the lip or cup 906 can expand outwardly, thus permitting the omega clip device 902 to maintain the relative positions of the mounting bracket 900 in close proximity to the sidewall of the junction box 910.

In FIG. 10, a mounting bracket 1000 with two different mounting devices 1002, 1004 is shown. The first mounting device, a tab 1002, is shown with a terminating knobbed portion and a short protrusion from the mounting bracket 1000.

Each of the extensions 11206 can be configured to recess within the body when a force is applied to each extension. When the force is removed, each extension 11206 can return to a position extending slightly outward from the lateral side of the body. A split opening 11208 alongside a substantial portion of the body 11202 and/or head portion 11204 can permit compression of certain portions of the pin 11200. In this manner, the pin 11200 can be inserted into a hole, for example, of an electrical junction box, mounting bracket or electrical accessory, and the pin 11200 can be retained within the hole. For instance, as the body 11202 of the pin 11200 passes through the hole, the contact force of the pin 11200 against the lateral sides of the hole compresses certain portions of the pin 11200 and applies a force to the extensions 11206, causing the extensions 11206 to recede within the body 11202 of the pin 11200. As the pin 11200 is suitably or fully inserted into the hole, the extensions 11206 may extend away from the lateral sides of the pin 11200 when the extensions 11206 are no longer in contact with the lateral sides of the hole. If the pin 11200 backed out of the hole, the extended extensions 11206 may prevent movement of the pin 11200 outward from the hole unless a force is applied to one or both of the extensions 11206 to recess the extensions into the body 11202 of the pin 11200.

In one embodiment, the split body 11202 and head portion 11204 of the pin 11200 can facilitate compression of the pin body 11202 and head portion 11204 during installation. In this manner, a compressed pin 11200 can be inserted into a relatively tight hole or space, and after insertion, the material may expand slightly to fill the hole or space, thus creating a relatively tight fit between the pin 11200 and the hole or space.

The pin 11300 shown in FIG. 113 functions similarly to the pin in FIG. 112, but has a slightly different shape. The pin 11300 in FIG. 113 also includes a split body 11302 and head portion 11304, and a pair of extensions 11306 on opposing lateral sides of the body 11302. In this embodiment, the extensions 11306 can be slightly larger than the extensions 11206 shown in FIG. 112.

FIGS. 114-117, and 121-129 illustrate example mounting brackets in accordance with various embodiments of the invention. FIGS. 114A, 114B, and 114C illustrate different views of an example T-shape mounting bracket 11400, also known as a far side support, for use with an electrical junction box or electrical accessory in accordance with an embodiment of the invention. Typically, the T-shape mounting bracket 11400 can be used with any number of electrical junction boxes and/or electrical accessories with a pair of spaced apart holes to receive a respective number of mounting pins and/or mounting devices associated with the mounting bracket. In this example, the upper portion of the mounting bracket 11400 can include a pair of spaced apart mounting pins 11402 or mounting devices. When the mounting pins 11402 and/or mounting devices are aligned with the corresponding holes in an electrical junction box and/or electrical accessory, the mounting pins 11402 or mounting devices can be inserted into the corresponding holes, and the relative positions of the mounting bracket 11400 and electrical junction box or electrical accessory can be maintained.

In the embodiment shown in FIGS. 114A, 114B, and 114C, an extended lower portion of the T-shape bracket 11400 can mount to surface, such as a wall stud, the floor, or other object. In this manner, the T-shape bracket 11400 can support a mounted electrical junction box or electrical accessory away from the surface to which the extended lower portion of the T-shape bracket 11400 is mounted to.

Also shown in FIGS. 114A, 114B, and 114C, the extended lower portion of the T-shape bracket 11400 can include a series of perforations 11404 or notches at predefined distances from the upper portion of the bracket. These perforations 11404 or notches can permit a user to break or cut the bracket to a predefined desired size or length.

In one embodiment, spaced apart mounting pins and/or mounting devices can be preconfigured and are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using a common mounting bracket with mounting devices, such as mounting pins.

The T-shape mounting bracket 11400 shown in FIGS. 114A, 114B, and 114C can include two previously installed mounting devices, such as 11402, though in other embodiments, a fewer or greater number of mounting devices can be employed. The mounting devices 11402 shown in FIGS. 114A, 114B, and 114C are shown by way of example only, and other mounting devices can be used in other embodiments. In use, the mounting bracket 11400 can mount adjacent to one of the walls of an electrical junction box or to an electrical accessory, when the mounting devices 11402 are inserted through respective holes in the walls of an electrical junction box or electrical accessory. After each mounting device 11402 is inserted through respective holes, the mounting devices 11402 can maintain the relative positions of the box or electrical accessory and mounting bracket 11400 in a substantially adjacent orientation. Other mounting brackets and associated hole configurations, sizes, dimensions, positions, and numbers of holes in an electrical junction box or electrical accessory are possible in accordance with embodiments of the invention.

FIGS. 118-120 illustrate views of example electrical accessories, such as cover or mud rings, also known as “retro rings,” in accordance with various embodiments of the invention. The example electrical accessories in FIGS. 119 and 120 can be snap fit to an electrical junction box or electrical accessory by way of a series of mounts that correspondingly fit within the recess or opening of an adjacent electrical junction box or electrical accessory. Other types of mounts can be used in accordance with certain embodiments of the invention.

FIG. 121 illustrates a perspective view of an example square C-shape mounting bracket 12100, also known as a box-to-box bracket, for use with an electrical junction box or electrical accessory in accordance with an embodiment of the invention. The bracket 12100 shown can be rectangular-shaped with an elongated or extended body with angled end portions at approximately 90 degrees with respect to the body. Typically, the square C-shape mounting bracket 12100 can be used with any number of electrical junction boxes and/or electrical accessories with a pair of spaced apart holes to receive a respective number of mounting pins and/or mounting devices associated with the mounting bracket. In this example, one end portion of the mounting bracket 12100 can include a pair of previously installed, spaced apart mounting pins 12102 or mounting devices. When the mounting pins 12102 and/or mounting devices are aligned with the corresponding holes in an electrical junction box and/or electrical accessory, the mounting pins 12102 or mounting devices can be inserted into the corresponding holes, and the relative positions of the mounting bracket 12100 and electrical junction box or electrical accessory can be maintained. An opposing end portion of the mounting bracket 12100 can include a pair of spaced apart mounting holes 12104. When the mounting holes 12104 are aligned with corresponding pins and/or mounting devices in an electrical junction box and/or electrical accessory, the holes 12104 can be mounted to the corresponding mounting pins or mounting devices, and the relative positions of the mounting bracket 12100 and electrical junction box or electrical accessory can be maintained.

In the embodiment shown in FIG. 121, an extended portion 12106 between the two angled end portions 12108 can separate the end portions 12108 at a predefined distance. For example, one end portion of the square C-shape bracket can mount to surface, such as a wall stud, the floor, or other object. In this manner, the square C-shape bracket 12100 can support a mounted electrical junction box or electrical accessory away from the surface to which the extended lower portion of the square C-shape bracket is mounted to.

In one embodiment, the spaced apart mounting pins and/or mounting devices as well as the spaced apart mounting holes are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using the square C-shape mounting bracket as a common mounting bracket with any number of electrical junction boxes and/or electrical accessories.

The C-shape mounting bracket 12100 shown in FIG. 121 can include two previously installed mounting devices, such as 12102, though in other embodiments, a fewer or greater number of mounting devices can be employed. The mounting devices 12102 shown in FIG. 121 are shown by way of example only, and other mounting devices can be used in other embodiments. In use, the mounting bracket 12100 can mount adjacent to one of the walls of an electrical junction box or to an electrical accessory, when the mounting devices 12102 are inserted through respective holes in the walls of an electrical junction box or electrical accessory. After each mounting device 12102 is inserted through respective holes, the mounting devices 12102 can maintain the relative positions of the box or electrical accessory and mounting bracket 12100 in a substantially adjacent orientation. Other mounting brackets and associated hole configurations, sizes, dimensions, positions, and numbers of holes in an electrical junction box or electrical accessory are possible in accordance with embodiments of the invention.

FIGS. 122A-122E illustrate views of another C-shape mounting bracket 12200, similar to the bracket 12100 shown in FIG. 121, but with mounting holes 12202 at both ends of the angled portions.

FIG. 123 illustrates a perspective view of an example L-shape mounting bracket 12300, also known as a box-to-box bracket, for use with an electrical junction box or electrical accessory in accordance with an embodiment of the invention. Typically, the L-shape mounting bracket 12300 can be used with any number of electrical junction boxes and/or electrical accessories with a pair of spaced apart holes to receive a respective number of mounting pins and/or mounting devices associated with the mounting bracket. In this example, a relatively short end portion of the mounting bracket 12300 can include a pair of previously installed, spaced apart mounting pins 12302 or mounting devices. When the mounting pins 12302 and/or mounting devices are aligned with the corresponding holes in an electrical junction box and/or electrical accessory, the mounting pins 12302 or mounting devices can be inserted into the corresponding holes, and the relative positions of the mounting bracket and electrical junction box or electrical accessory can be maintained.

In the embodiment shown in FIG. 123, an extended longer portion 12304 of the L-shape bracket 12300 can mount to surface, such as a wall stud, the floor, or other object. In this manner, the L-shape bracket 12300 can support a mounted electrical junction box or electrical accessory away from the surface to which the extended lower portion of the L-shape bracket is mounted to.

Also shown in FIG. 123, the extended longer portion 12304 of the L-shape bracket 12300 can include a series of perforations 12306 or notches at predefined distances from the relatively short end portion of the bracket. These perforations 12306 or notches can permit a user to break or cut the bracket to a predefined desired size or length. Each of the segments 12308 between the perforations 12306 or notches can include a series of mounting holes 12310, such as 2 holes, sized to receive a mounting pin, mounting device, or other fastening device.

In one embodiment, the spaced apart mounting pins and/or mounting devices are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using the L-shape bracket as a common mounting bracket with any number of electrical junction boxes and/or electrical accessories.

The L-shape mounting bracket 12300 shown in FIG. 123 can include two previously installed mounting devices, such as 12302, though in other embodiments, a fewer or greater number of mounting devices can be employed. The mounting devices 12302 shown in FIG. 123 are shown by way of example only, and other mounting devices can be used in other embodiments. In use, the mounting bracket 12300 can mount adjacent to one of the walls of an electrical junction box or to an electrical accessory, when the mounting devices 12302 are inserted through respective holes in the walls of an electrical junction box or electrical accessory. After each mounting device 12302 is inserted through respective holes, the mounting devices 12302 can maintain the relative positions of the box or electrical accessory and mounting bracket in a substantially adjacent orientation. Other mounting brackets and associated hole configurations, sizes, dimensions, positions, and numbers of holes in an electrical junction box or electrical accessory are possible in accordance with embodiments of the invention.

FIGS. 124A-124E illustrate views of a L-shape mounting bracket 12400, similar to the bracket 12300 shown in FIG. 123, but with mounting holes 12402 in the relatively short end of the bracket 12400.

FIG. 125 illustrates another example square C-shape bracket 12500, also known as a box-to-box bracket, that can function similar to the mounting bracket 12100 shown and described in FIG. 121. In the embodiment shown in FIG. 125, the extended portion 12502 between the end portions 12504 is relatively short and can be machined to a predefined length depending on the intended use for the bracket 12500. Further, the bracket shown in FIG. 125 includes four previously installed mounting pins 12506 or mounting devices, though any number of pins or devices can be used with the bracket.

FIG. 127 illustrates a perspective view of an example L-shape mounting bracket 12700, also known as a box-to-box bracket, for use with an electrical junction box or electrical accessory in accordance with an embodiment of the invention. Typically, the L-shape mounting bracket 12700 can be used with any number of electrical junction boxes and/or electrical accessories with a pair of spaced apart holes to receive a respective number of mounting pins and/or mounting devices associated with the mounting bracket. In this example, one end portion of the mounting bracket 12700 can include a pair of previously installed, spaced apart mounting pins 12702 or mounting devices. When the mounting pins 12702 and/or mounting devices are aligned with the corresponding holes in an electrical junction box and/or electrical accessory, the mounting pins 12702 or mounting devices can be inserted into the corresponding holes, and the relative positions of the mounting bracket 12700 and electrical junction box or electrical accessory can be maintained. An opposing end portion of the mounting bracket 12700 can include a pair of spaced apart mounting holes 12704. When the mounting holes 12704 are aligned with corresponding pins and/or mounting devices in an electrical junction box and/or electrical accessory, the holes 12704 can be mounted to the corresponding mounting pins or mounting devices, and the relative positions of the mounting bracket 12700 and electrical junction box or electrical accessory can be maintained.

In the embodiment shown in FIG. 127, one end portion of the L-shape bracket 12700 can mount to surface, such as a wall stud, the floor, or other object. In this manner, the L-shape bracket 12700 can support a mounted electrical junction box or electrical accessory away from the surface to which the extended lower portion of the L-shape bracket is mounted to.

In one embodiment, the spaced apart mounting pins and/or mounting devices as well as the spaced apart mounting holes are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using the L-shape mounting bracket as a common mounting bracket with any number of electrical junction boxes and/or electrical accessories.

The L-shape mounting bracket 12700 shown in FIG. 127 can include two previously installed mounting devices, such as 12702, though in other embodiments, a fewer or greater number of mounting devices can be employed. The mounting devices 12702 shown in FIG. 127 are shown by way of example only, and other mounting devices can be used in other embodiments. In use, the mounting bracket 12700 can mount adjacent to one of the walls of an electrical junction box or to an electrical accessory, when the mounting devices 12702 are inserted through respective holes in the walls of an electrical junction box or electrical accessory. After each mounting device 12702 is inserted through respective holes, the mounting devices 12702 can maintain the relative positions of the box or electrical accessory and mounting bracket in a substantially adjacent orientation. Other mounting brackets and associated hole configurations, sizes, dimensions, positions, and numbers of holes in an electrical junction box or electrical accessory are possible in accordance with embodiments of the invention.

In one aspect of an embodiment, any of the mounting brackets and electrical junction boxes in accordance with embodiments of the invention described above can meet the standards specified by UL (Underwriters' Laboratories) 514A.

One will recognize that certain mounting brackets in accordance with embodiments of the invention can be used with plaster ears, old work clips, far side box supports, and other electrical, data, communication, and control accessories.

One will recognize that other configurations for mounting brackets in accordance with embodiments of the invention are possible.

FIGS. 128A-128D illustrate views of a square L-shape mounting bracket 12800, similar to the bracket 12700 shown in FIG. 127, but with four total mounting holes 12802 in the bracket 12800.

FIG. 129 is a perspective views of a square L-shape mounting bracket 12900, similar to the bracket 12700 shown in FIG. 127, but with several edge and corner tapers, and a geometrically-shaped hole 12902 in the bracket 12900.

FIG. 130 illustrates a chart describing example configurations for knockout arrangements in electrical junction boxes according to various embodiments of the invention. Several different knockout arrangements are described for different size and depth electrical junction boxes, including handy boxes, 4″ square, octagon-shape, 4″ square, and 5″ square, though embodiments of the invention should not be limited to these sizes only. For each of the configurations, the selected knockout arrangements are optimized for providing different knockout options to a user on one or more sides of the electrical junction box.

In one embodiment, a screwdriver tip recess can be provided on the face of central knockout. The recess can be shaped to fit the tip of a screwdriver or other instrument, and can facilitate the removal of the knockout when a force is applied to the recess with the screwdriver or other instrument.

In one embodiment, a knockout arrangement can include a series of contact points arranged at about 90 degrees along the circumference of the knockout. For example, in a concentric or eccentric knockout arrangement, the outer knockout can include 4 contact points with the associated electrical junction box, wherein the 4 contact points are approximately spaced at the about 0, 90, 180, and 270 degree orientations along the circumference of the outer knockout.

In one embodiment, a concentric or eccentric knockout arrangement can have an alternating profile. That is, a knockout arrangement with multiple concentric or eccentric knockouts can alternate profile heights with an inner knockout being raised, a middle knockout being recessed with respect to the inner knockout, and an outer knockout being raised with respect to the middle knockout.

In certain embodiments, a concentric or eccentric knockout arrangement with an alternating profile can be compressed to stiffen the arrangement to minimize accidental removal of one or more of the knockouts.

FIGS. 131-132 illustrate views of another example mounting device for an electrical junction box in accordance with an embodiment of the invention. The example mounting pin 13100 shown in FIGS. 131 and 132A-132D can be used to connect at least two electrical accessories together. Suitable electrical accessories can include, but are not limited to, an electrical junction box, a mounting bracket, and an electrical accessory. For example, a pair of mounting pins can be inserted into a respective pair of spaced apart holes, spaced at a predefined universal distance, in a side wall of an electrical junction box to facilitate using a common mounting bracket to mount adjacent to the side wall of the electrical junction box.

The pin 13100 shown in FIG. 131 can include a split elongated body 13102 with a head portion 13104. On opposing lateral sides of the body, a pair of flexible extensions 13106 can be located. Each of the extensions 13106 can be configured to recess within the body when a force is applied to each extension. When the force is removed, each extension 13106 can return to a position extending slightly outward from the lateral side of the body. A split opening 13108 alongside a substantial portion of the body 13102 and/or head portion 13104 can permit compression of certain portions of the pin 13100. In this manner, the pin 13100 can be inserted into a hole, for example, of an electrical junction box, mounting bracket or electrical accessory, and the pin 13100 can be retained within the hole. For instance, as the body 13102 of the pin 13100 passes through the hole, the contact force of the pin 13100 against the lateral sides of the hole compresses certain portions of the pin 13100 and applies a force to the extensions 13106, causing the extensions 13106 to recede within the body 13102 of the pin 13100. As the pin 13100 is suitably or fully inserted into the hole, the extensions 13106 may extend away from the lateral sides of the pin 13100 when the extensions 13106 are no longer in contact with the lateral sides of the hole. If the pin 13100 backed out of the hole, the extended extensions 13106 may prevent movement of the pin 13100 outward from the hole unless a force is applied to one or both of the extensions 13106 to recess the extensions into the body 13102 of the pin 13100.

In one embodiment, the split body 13102 and head portion 13104 of the pin 13100 can facilitate compression of the pin body 13102 and head portion 13104 during installation. In this manner, a compressed pin 13100 can be inserted into a relatively tight hole or space, and after insertion, the material may expand slightly to fill the hole or space, thus creating a relatively tight fit between the pin 13100 and the hole or space.

The pin 13100 shown in FIG. 132 functions similarly to the pin in FIG. 112, but has a slightly different shape.

FIGS. 133-134 illustrate views of another example modular bracket for an electrical junction box in accordance with an embodiment of the invention. The bracket 13300 shown can be rectangular-shaped with an elongated or extended body with angled end portions parallel to the body. Typically, the mounting bracket 13300 can be used with any number of electrical junction boxes and/or electrical accessories with a pair of spaced apart holes to receive a respective number of mounting pins and/or mounting devices associated with the mounting bracket. In this example, the body of the mounting bracket 13300 can include two mounting holes 13302, and in other embodiments, could include one or more previously installed, spaced apart mounting pins or mounting devices. When the mounting holes 13302 are aligned with one or more corresponding mounting pins and/or mounting devices associated with an electrical junction box and/or electrical accessory, the mounting pins or mounting devices can be inserted into the corresponding holes, and the relative positions of the mounting bracket 13300 and electrical junction box or electrical accessory can be maintained. Opposing end portions of the mounting bracket 13300 can include additional mounting holes and/or fastener holes. When the additional mounting holes and/or fastener holes are aligned with corresponding pins and/or mounting devices in an electrical junction box and/or electrical accessory, the additional mounting holes and/or fastener holes can be mounted to the corresponding mounting pins or mounting devices, and the relative positions of the mounting bracket 13300 and electrical junction box or electrical accessory can be maintained.

In the embodiment shown in FIG. 133, an extended portion 13304 between the two angled end portions 13306 can separate the end portions 13306 at a predefined distance. For example, one end portion of the bracket can mount to surface, such as a wall stud, the floor, or other object. In this manner, the bracket 13300 can support a mounted electrical junction box or electrical accessory away from the surface to which the extended lower portion of the bracket is mounted to.

In one embodiment, the spaced apart mounting holes are generally spaced apart at approximately the same or similar distance, such as a predefined universal distance, to facilitate using the mounting bracket as a common mounting bracket with any number of electrical junction boxes and/or electrical accessories.

The mounting bracket 13300 shown in FIG. 133 can include two mounting holes, such as 13302, though in other embodiments, a fewer or greater number of mounting holes can be employed. The mounting holes 13302 shown in FIG. 121 are round and shown by way of example only, and other shape can be used in other embodiments. In use, the mounting bracket 13300 can mount adjacent to one of the walls of an electrical junction box or to an electrical accessory, when the mounting holes 13302 receive respective mounting devices associated with the wall of an electrical junction box or electrical accessory. After each mounting device is inserted through respective mounting holes 13302, the mating of the mounting devices and mounting holes can maintain the relative positions of the box or electrical accessory and mounting bracket 13300 in a substantially adjacent orientation. Other mounting brackets and associated hole configurations, sizes, dimensions, positions, and numbers of holes in an electrical junction box or electrical accessory are possible in accordance with embodiments of the invention.

FIGS. 135A-135D show another example mounting device in accordance with an embodiment of the invention. The mounting device shown in FIGS. 135A-135D is a wave spring 13502. In this embodiment, the wave spring 13502 is annular-shaped. Though the wave spring can be made from a relatively flat piece of material, the spring 13500 can include one or more curves or waves that disrupt the generally flat profile of the spring 13500 as shown in FIG. 135D. When the spring 13500 is compressed towards a relatively flat profile, the curves or waves in the spring 13500 generally resist the compression force. FIGS. 136A-136H show another example mounting device in accordance with an embodiment of the invention. The mounting device shown in FIGS. 136A-136H is a vibration lock pin 13600. The pin 13600 may be used in conjunction with a wave spring, such as 13500 in FIGS. 135A-135D. The example mounting device or pin 13600 shown in FIGS. 136A-136H can be used to connect at least two electrical accessories together. Suitable electrical accessories can include, but are not limited to, an electrical junction box, a mounting bracket, and an electrical accessory. For example, a pair of mounting pins can be inserted into a respective pair of spaced apart holes, spaced at a predefined universal distance, in a side wall of an electrical junction box to facilitate using a common mounting bracket to mount adjacent to the side wall of the electrical junction box.

The pin 13600 shown in FIG. 136A can include a split elongated body 13602 with a head portion 13604. On opposing lateral sides of the body, a pair of flexible extensions 13606 can be located. Each of the extensions 13606 can be configured to recess within the body when a force is applied to each extension. When the force is removed, each extension 13606 can return to a position extending slightly outward from the lateral side of the body. A split opening 13608 alongside a substantial portion of the body 13602 and/or head portion 13604 can permit compression of certain portions of the pin 13600. In this manner, the pin 13600 can be inserted into a hole, for example, of an electrical junction box, mounting bracket or electrical accessory, and the pin 13600 can be retained within the hole. For instance, as the body 13602 of the pin 13600 passes through the hole, the contact force of the pin 13600 against the lateral sides of the hole compresses certain portions of the pin 13600 and applies a force to the extensions 13606, causing the extensions 13606 to recede within the body 13602 of the pin 13600. As the pin 13600 is suitably or fully inserted into the hole, the extensions 13606 may extend away from the lateral sides of the pin 13600 when the extensions 13606 are no longer in contact with the lateral sides of the hole. If the pin 13600 backed out of the hole, the extended extensions 13606 may prevent movement of the pin 13600 outward from the hole unless a force is applied to one or both of the extensions 13606 to recess the extensions into the body 13602 of the pin 13600.

In one embodiment, the split body 13602 and head portion 13604 of the pin 13600 can facilitate compression of the pin body 13602 and head portion 13604 during installation. In this manner, a compressed pin 13600 can be inserted into a relatively tight hole or space, and after insertion, the material may expand slightly to fill the hole or space, thus creating a relatively tight fit between the pin 13600 and the hole or space.

The pin 13600 shown in FIGS. 136A-136H functions similarly to the pin in FIG. 112, but has a slightly different shape.

In one embodiment, the pin 13600 can be used with the mounting device or wave spring 13500 shown in FIGS. 135A-135D, similar to the configuration shown in FIG. 136D. In this configuration, the wave spring can compress as needed between two adjacent electrical accessories to create a relatively tight fit between the adjacent accessories.

FIGS. 137A-137J show another example mounting device in accordance with an embodiment of the invention. This mounting device is similar to the pin 13600 shown in FIGS. 136A-136H.

FIGS. 138-146 illustrate an example method in accordance with an embodiment of the invention,

In a first operation of the method, as shown in FIG. 138, a wall of a first electrical junction box is selected. In this example, a side wall of a handy box is selected.

In a second operation of the method, as shown in FIG. 139, a wall of a second electrical junction box is selected. In this example, a side wall of a square box is selected and overlaid on top of the depiction of the wall of the first electrical junction box.

In a third operation of the method, as shown in FIG. 140, a determination is made of a common area between the first electrical junction box and the second electrical box.

In a fourth operation of the method, as shown in FIG. 141, a wall of a third electrical junction box is selected.
